NuSmile BioFlx is the FIRST flexible, durable, and esthetic pediatric crown in the market. With tooth preparation that lies between Zirconia and a traditional SSC preparation, BioFlx offers pediatric dentists the perfect blend of tooth-colored restoration and ease of placement. BioFlx crowns are made of a biocompatible, high-impact, high-strength hybrid material with the flexibility and adaptability to provide an active fit to the tooth. The crowns are pre-contoured and pre-crimped for tooth preparation and handling like an SSC, saving chair time.
